william runs 40 yards in 4.5 seconds. at the same pace how long will he take to run 100yards?
Answers
Answer:
11.25 seconds
Step-by-step explanation:
first, we need to figure how how far william can run per second
we can find this by 40 ÷ 4.5
= 8.889 per second
so we know that 8.889 • s (seconds) = 100
8.889s = 100 divide both sides by 8.889
s = 11.25 seconds
Answer:
William will take 11.25 seconds to run 100 yards
Step-by-step explanation:
Constant Rate
William runs 40 yards in 4.5 seconds. The rate of change of the distance is
[tex]\frac{40}{4.5}[/tex]
To run 100 yards, we divide by the rate obtained above:
[tex]\displaytstyle \frac{100}{\frac{40}{4.5}} =100*\frac{4.5}{40} =11.25[/tex]
William will take 11.25 seconds to run 100 yards

A civil servant had a salary of Rs. 9600. Tax up to
Rs. 85000 per year would be exempted. If he paid
Rs. 377.50 as a tax per month, how much percent of
tax was imposed ?
(Ans: 15 %
Answers
Answer:
Step-by-step explanation:
The question is misleading. It was not specified that his salary is Rs 9,600 per month. That is 115,200 yearly. Of that, 115,200- 85,000 = 30,200 is taxable.
tax = Rs 377.50/month = Rs 4,530/year
4,530/30,200 = 0.15 = 15%

Answers
Answer:
x^3 - 8
Step-by-step explanation:
X(x^2 + 2x + 4 ) - 2 (x^2 + 2x + 4)
Then you expand by distributing terms
X^3 + 2 x^2 + 4x - 2 ( x^2 + 2x + 4)
Collect like terms
X^3 + (2x^2 - 2x^2) + (4x - 4x) - 8

what is Pythagorean triples
Answers
A Pythagorean triple consists of three positive integers a, b, and c, such that a2 + b2 = c2. Such a triple is commonly written (a, b, c), and a well-known example is (3, 4, 5). If (a, b, c) is a Pythagorean triple, then so is (ka, kb, kc) for any positive integer k.
Answer:
A pythagorean triplet is a set of three numbers which satisfies the pythagoreus theorum - ( a^2+b^2=c^2).
Example:
3, 4 and 5
3^2 + 4^2 = 5^2

What are the coordinates of the image of point T(2,4) over the transformation D(1/2,R), where R(6,-2) is the center. X= ? Y= ?
Answers
9514 1404 393
Answer:
T'(4, 1)
Step-by-step explanation:
The dilation transformation around a center not the origin is ...
T' = k(T -R) +R . . . . for dilation factor k and center R
This can be simplified to ...
T' = 1/2T -1/2R +R = 1/2T +1/2R = (T +R)/2
Using the given point values, we find the image point to be ...
T' = ((2, 4) +(6, -2))/2 = (8, 2)/2 = (4, 1)
The image point is T'(4, 1).
A soccer team gets three points for a win, one point for a tie, and zero points for a loss. The team plays ten games and has three more wins than losses. What is the greatest possible number of points the team could have?
Answers
Answer: 19.
Step-by-step explanation:
The highest you can go is 6 and 3 because you can't do 7 and 4. 6 wins would add up to 18 points. The one game that is missing we can say could be a tie, which would add 1 point, making it 19 possible points.
Answer:
Highest number of wins and losses can only be 6 & 3 and if u take 7 & 4 as taking 7&4 will make total 11 and we know that there was only 10 games.
So we can conclude like this
Number of wins: 6
Number of losses: 3
Number of draws: 1
Thus the points will be, (6*3)+(3*0)+(1*1)
18+0+1
=19 points
Suppose a loaded die has the following probability model: If this die is thrown and the top face shows an odd number, what is the probability that the die shows a 1
Answers
Answer:
the probability is 0.6
Step-by-step explanation:
The computation is shown below:
Let us assume the X would be the number appear on the top face
Now
= P(X = 1) ÷ P(X = 0)
= 0.3 ÷ 0.3 + 0.1 + 0.1
= 0.3 ÷ 0.5
= 0.6
hence, the probability is 0.6

The function f(x) =5x coverts x nickels to pennies. Find a function that converts X Pennys to Nichols then convert 50 pennies to Nichols. 
Answers
Answer:
[tex]f'(x) = \frac{1}{5}x[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 5x[/tex] --- Nickel to Penny
Required
Determine the function that converts penny to nickel
This question implies that we determine the inverse of the function.
We have:
[tex]f(x) = 5x[/tex]
Represent f(x) with y
[tex]y = 5x[/tex]
Swap the positions of x and y
[tex]x = 5y[/tex]
Make y the subject by dividing both sides by 5
[tex]\frac{1}{5}x = \frac{5y}{5}[/tex]
[tex]\frac{1}{5}x = y[/tex]
[tex]y =\frac{1}{5}x[/tex]
Replace y with f'(x)
[tex]f'(x) = \frac{1}{5}x[/tex]
Hence, the function that converts x pennies to nickels is [tex]f'(x) = \frac{1}{5}x[/tex]
